Thank you again for further info hopefully I will get lucky and come across some old news about these quad posters but at the moment it's a real struggle to find any information on the back by popular demand posters especially in quad format for some reason info on U.S./portrait posters are easier to find.
The link shows how much people are asking for the original release the U.S./portrait versions are going for over here the in UK. It would be great if I had seen any quad posters online but it's like getting blood from a stone. If I do find any information I'll keep you updated, I feel like this is going to become quite the investigation so it will be fun.
